Prepare Heater
NOTICE: Incorrect heating temperature can result in
questionable fusion joints. Check heater plates
periodically with a pyrometer and make necessary
adjustments.
Refer to the "Maintenance" section of this manual for instructions
how to adjust heater temperature.
Check heater surface temperature with a pyrometer.
Refer to the pipe manufacturer's recommendations or appropriate
joining standard for proper heater temperature.
IMPORTANT: The dial thermometer on the heater indicates internal
temperature which varies from the actual surface temperature.
The dial thermometer can be used as reference once the surface
temperature has been verified and is never a substitute for actual
surface temperature.

Inserting Heater
The heater is not explosion proof. Operation
of heater in an explosive atmosphere without
necessary safety precautions will result in serious
injury or death.
If operating in an explosive atmosphere, heater should be brought
up to temperature in a safe environment, then unplugged before
entering the explosive atmosphere for fusion.
Use a clean nonsynthetic cloth to clean the butt fusion heater
adapter surfaces.
Verify heater temperature by noting the reading on the dial
thermometer.
Place the heater on the main centered beneath the fitting base,
and then place the Flexible Heat Shield between the heating tool
and the fitting base. (This step usually requires an assistant to
handle the Flexible Heat Shield).
IMPORTANT: A heat shield may not be required for fittings 3" and
smaller.
